摘要：

In this paper, we proposed a double-level error resilient joint source-channel coding scheme for image transmission. Characteristically, we inserted one coordinative component named error resilient entropy coding (EREC) between source coding and channel coding to achieve additional error resilient capability. Based on the novel architecture, we proved that, in the aspects of computational complexity, coding redundancy and furthermore the decoding performance of image transmission, our scheme outperformed either separate source and channel coding scheme or joint source-channel coding scheme with synchronization words.
